Please help with Avatar resizing

[Copepod]

I finally got some help sort-of fixing my printer so I could scan the picture I wanted for my Avatar. Problem is, I can't get the size right. I downloaded the link on resizing, but still can't get it right. Having slow dial-up doesn't help a bit. I tried to make the scan 80x80 pixels and thought it would fit when transferred, but as you can see, it is sadly wanting in size.

Please help me...I don't have the technical knowledge.

Thanks
